I bought a lightly used S & W model 669 9mm semi (1980's) and found out that there was a recall issued because of a defective safety. It exhibits the problem described in the recall. I called S & W and they are sending me a return slip. I'm not sure if I want to go through the "wait" associated with a return to the manufacturer. Do you think this problem could be fixed by a local gunsmith? Thanks for any help!
